Mirabel's gift was never meant to manifest, which is why she didn't explicitly receive a gift at the end of Encanto. Rather, Mirabel herself is the gift, and it's thanks to her that the Madrigal family is whole again.
For instance, Mirabel's sister Luisa (Jessica Darrow) gets super strength, and her cousin Dolores (Adassa) has the power of keen hearing. However, in the film, Mirabel doesn't get a gift, which causes problems in her relationship with Abuela Alma (María Cecilia Botero).
Returning to Antonio's ceremony, it is clear in a close-up of him grabbing the knob that it has an A etched into it. So, Mirabel did get her door in a way. Her door is the front gate of the Casa Madrigal because she used her gift to teach, heal and rebuild the family like the house was rebuilt.
Encanto's Mirabel Has Always Had Her Gift
However, Encanto puts a twist on it by not calling Mirabel the brains. Throughout Encanto, Mirabel never needed supernatural gifts to figure out why Casita was deteriorating. Mirabel's gift is her intelligent determination, and she had that all along.
The ending reveals Mirabel's true gift: the miracle itself. She keeps her family's gifts alive and helps them flourish despite not having tangible powers. When she helps Isabela accept herself, the cracks in Casita heal and her sister discovers new abilities.
But in the film, when Mirabel finally is able to put her hand on a doorknob after her childhood attempt fails, it brings the magical casita of the Madrigals back to life. Perhaps her gift is the greatest one, the power to keep her family, their home and all their magical separate gifts, together and thriving.
Like Mirabel, Abuela wasn't granted a gift by the Encanto, but instead is the holder of power for the entire family. As the keeper of the candle, Abuela oversees the magic of the Encanto and its community. However, it isn't actually the candle that keeps the magic alive, it is the Madrigal family.
Mirabel, at an undefined point in time after the events of the first movie, was told by her abuela Alma, as she was dying, that she was chosen to be the next matriarch of the family, as a thank you for saving the miracle and helping mend the family back together.
Why did Mirabel's door disappear? Mirabel's door disappeared because she was already where she needed to be in order to receive her gift. Remember, Mirabel's gift was keeping the family together through her amazing ability to understand and feel the family's happiness or lack of it.
Encanto 2 may just explore how powerful each Encanto character is when they don't actually have their unique gifts. This opens the door for Mirabel, who hasn't had powers her whole life, to help everyone else on their way. Of course, the Madrigals could still maintain their powers in Encanto 2.
The most reasonable explanation for Abuela having her own door (which, is worth noting, glows like any other even though she doesn't have powers) is that the candle and Casita gave it to her because she's the Candle Keeper and “Miracle Guardian”, as was as the leader of the Madrigal family.
According to the theory, Mirabel sabotaged her own gift accidentally during her ceremony. After touching a magical candle, Mirabel wipes her hands on her clothes, and fans speculated that this was the reason the young Madrigal didn't get powers. One of the Encanto directors recently debunked the Mirabel theory.
Bruno is a bit eccentric, and one could argue that Bruno struggles with mental health concerns, exhibiting tics of “knock-knock-knock on wood” among others. Mirabel also learns that her sister Luisa is under tremendous pressure that causes her great anxiety.
Though the company has been busy announcing sequels in development for Frozen, Toy Story, and Zootopia, that doesn't mean that Disney doesn't plan to release one for Encanto too. Zootopia, after all, first hit theaters in 2016, and 2023 is the first a sequel has been officially confirmed for the movie.
Not giving Mirabel a gift was Casita's way to “punish” Abuela, forcing her to reflect on what she had done to her family. At the same time, as Casita also loved the family, it didn't leave Mirabel entirely powerless, and it gave her its own magic, allowing her to communicate with Casita.
Abuela Was In the Vision
When Mirabel and Bruno (John Leguizamo) are viewing his vision of her, she begs him to continue, so she can see the end. The vision shows flashes of the future, and eventually reveals an image of Isabel (Diane Guerrero) and Mirabel hugging.
"Mirabel and [Abuela] are the only two people to be able to communicate with the Casita in the movie. This could show some sort of special relationship with the Casita and in turn, the magic in the house," they add.
The underlying tension and fracture in family relationships also cause the entire magical house to crumble, but the strengthening of the Madrigals' relationships results in the resurrection of the Casita.
i think abuela subconsciously chose isabella to be her favorite grandchild. because of the trauma that had been weighing on her for decades. she saw her younger self. within isabella yes abuela desperately wanted to use their family's magic to preserve their new home but she also wanted to see her descendants.
Abuela Alma tells Bruno to look into the future on why Mirabel didn't get a gift. Bruno is the youngest of the fraternal triplets and the only son of Alma and Pedro, his siblings being Julieta and Pepa.
“I will never be good enough for you, will I?” ~ Mirabel. Mirabel's deepest wound is that Abuela Madrigal wants her to be someone who she is not. She would love her abuela to love her for who she is but is willing to let go of abuela's approval to be herself.
Bruno's tragic 10-year-old vision was not showing two possibilities like Mirabel thought. Instead, it was showing a magical before and after picture. Similar to modern before and after photos, the picture of Casita being shattered was revealed when Mirabel tilted the prophecy to the left.
While Encanto doesn't have a traditional Disney villain, Dolores Madrigal seems the closest to fulfill that role, especially with how she tries to ruin things for her cousin, Isabela.
Having married into the family, Félix has no magical gift of his own. However, he can be quite agile and quick on his feet.
